Datasheet Library by Series
Most buyers arrive here with one question. Does this part fit the design I already have? Every waterproof connector datasheet below answers it with rated current, voltage, contact resistance, cable range, temperature limits and the approval list, rather than a marketing summary. Each PDF is the document our own engineers work from, so what you read is what we build to.

Datasheet Guide
What a Waterproof Connector Datasheet Tells You
A waterproof connector datasheet is only useful if you know which line answers your question. Six fields decide whether a part fits your electrical, mechanical and compliance requirements.
01
Rated Current & Voltage
Rated current and voltage come with a standard attached. The M686 series carries 24A at 450VAC under IEC and NSW, and 10–15A at 300VAC under ETL. Both figures are correct. They come from different test programmes, so quote the one your certification body or end customer recognises, and read the datasheet row rather than relying on a product title.
02
Cable Range
Cable range is listed in mm² and AWG, and it is often split by region. The M686-3 series accepts 0.5–2.5 mm² under European and Australian practice, or SJOW 14–18 AWG under American practice. A cable outside the stated range can affect the seal gland even when the connector can still be physically closed.
03
IP Rating & Test Conditions
The IP rating should be read together with its test conditions. IP68 indicates protection demonstrated under specified immersion conditions, while the datasheet should state the relevant depth, duration or applicable test criteria. Compare those conditions with your actual installation rather than treating every IP68-rated connector as identical. See the IP code reference for an overview of how the rating system is structured.
04
Working Temperature
Working temperature appears in the waterproof connector datasheet as a class or a range. The M686 junction boxes are rated T105 and the MC4 connector T100, while the CN series energy storage connectors are specified from −40°C to 125°C. Match the rating against the temperature the installed connector may actually experience, including nearby equipment and surfaces.
05
Contact Resistance
Contact resistance indicates the electrical resistance across the connection and is an important indicator when evaluating losses and heat generation. The CN series energy storage connectors are specified at ≤0.5 mΩ, measured at 100 mA. Tracking this value during production inspection can also help identify changes in contact quality, plating or crimp performance.
06
Approvals & Compliance
The approval list helps determine whether a connector fits the compliance requirements of your product or target market. The M686 family includes certifications and declarations such as ENEC, CE, UKCA, ETL, NSW, CB and RoHS, while the MC4 solar connector documentation lists CE and RoHS. If your project requires a specific approval that is not listed, confirm it before designing the connector into your system.
Engineering tip: Do not select a waterproof connector from its current rating or IP rating alone. Cable size, temperature, test conditions, electrical resistance and required approvals should be checked together against the actual application.
How to Use These Files When You Replace an Existing Connector
Replacing a connector that already works is a smaller job than designing one in, but it has its own traps. Work through the waterproof connector datasheet in this order.
Match the interface, not the appearance. A three pin waterproof connector from another brand can share the housing shape and still differ in pin spacing or keyway. Pull the mating dimensions from the drawing inside the datasheet and check them against the part on your bench.
Check the cable range inside the waterproof connector datasheet against the cable you actually buy. A part specified for 0.5 to 2.5mm2 will not seal a 4.0mm2 cable, and the difference only shows up at the immersion test or, worse, in the field.
Compare ratings under the same standard. If your existing part is rated at 16A under one programme and the replacement is quoted at 24A under another, the two numbers are not sitting on the same ruler. Line them up before you decide the replacement is heavier duty.
Confirm the panel cut-out. The M686 range and the threaded connector families use different hole sizes, so a swap can mean re-machining a panel that is already painted.
Ask for a sample before the production order. Fit it with your own cable, torque it to the figure on the sheet and put it through whatever your incoming inspection covers. A sample that passes on the bench is cheaper than a container that fails at the customer.
CAD & Engineering Files
Drawings and 3D STEP Files on Request
A waterproof connector datasheet gives you ratings and general arrangement drawings. It does not always include a STEP file that can be dropped directly into an enclosure model, and some series do not yet have a public datasheet. In both cases, tell us what you are designing and we can provide the appropriate engineering file for the model you are evaluating.
What We Can Send
- 2D drawings in PDF or DXF, including panel cut-out, mounting hole positions and mating dimensions.
- 3D STEP models of the plug and receptacle for enclosure clearance checks, assembly planning and cable routing.
- Panel cut-out templates sized for laser cutting, punching or machining.
- Supporting test data behind a rating where it is available for the specific model being quoted.
What Helps Us Answer in One Reply
- The part number, or the code of the connector you are replacing.
- Your panel thickness and intended mounting orientation.
- The CAD format your design or engineering system can read.
- Whether the drawing will be shared with your own customer, so the correct level of engineering detail can be provided.

Ask for any of these models and we can provide the corresponding waterproof connector datasheet with ratings, dimensions and the approval information for the exact part being quoted. In the meantime, the screw waterproof connector page carries specification tables for the M682 to M685 range. You can also review the LED surge protective device , manual service disconnect and battery busbar connector product pages for currently published specifications.
Certificates and Test Reports
Two different things travel with an order. Product certificates show that a part has been type tested to a standard. Test reports show what a specific batch measured. Neither replaces the waterproof connector datasheet for the model you are ordering.
On the system side we hold ISO 9001, IATF 16949 and ISO 13485. Across the product range there are UL, CE, RoHS, CQC, ENEC, ETL, NSW, CB, TUV and UKCA approvals. Signed copies are collected on our certificates page.
Incoming and outgoing checks run on an insertion force tester, a dielectric withstand tester, a salt spray chamber, a waterproof test chamber, a 2.5D projection measuring system, a Vickers hardness tester, a plating thickness gauge and an insulation resistance meter. What those instruments measure is what appears on the datasheet, which is why every rating we publish has a measurement behind it.
If your qualification file references a standard or a clause we have not listed, send the waterproof connector datasheet you are working from before you order and we will confirm what we can provide. That conversation is faster and cheaper than finding the gap at an audit.
Waterproof Connector Datasheet FAQ
Quick answers to common questions about datasheet revisions, electrical ratings, CAD files, unpublished models, file formats, certificates and supporting test documentation.
There is a revision date on the last page of every waterproof connector datasheet we publish. We update the PDFs whenever a part changes, so the version you download today is the one we are currently shipping to. If you are holding an older copy and the model code matches, send it to us and we will confirm whether anything that matters to your design has changed.
Both are, under different standards. 24A at 450VAC is the IEC and NSW figure. 10–15A at 300VAC comes from ETL testing. A current rating should always be quoted together with the standard under which it was measured, so use the figure recognised by your certification body or end customer.
Yes, for production models. Send the part number, your panel thickness and the format your CAD system reads. We can provide a STEP model or a dimensioned 2D drawing for the model you are evaluating, usually with the panel cut-out included. Ask for what you need and we will confirm which files can be released.
For several series, yes, even when the file has not yet been published publicly. The M682 to M685 waterproof connectors, the LED surge protection range, the MSD-350, and the bolt and copper bar connectors all have drawings and rating tables that can be supplied on request. Send the model code and the values you need to confirm.
Published datasheets are supplied as PDF files. Specification rows are written in English, with some value names also shown in Chinese on certain sheets, and dimensions are given in millimetres. You can print the sheet, mark it up and send it back to us with your engineering questions.
Datasheets include ratings and approval names, but not normally the underlying test reports. Product certificates are published on our certificates page . Batch test reports may accompany an order where applicable. If your compliance file requires evidence against a specific clause, tell us the clause before ordering and we will confirm what can be supplied. Still looking for a waterproof connector datasheet that is not listed here? Send the model code and the values you need to confirm. Request a datasheet .
For engineering projects: include the model number, required rating or dimension, target certification and CAD format in your enquiry. This usually allows the correct file to be identified without additional back-and-forth.
